Abstract

The effects of an externally applied magnetic field on the photonic band structure of a periodic medium composed of vacuum and metallic or semiconducting materials are studied. Specifically, a waveguide formed from perfectly conducting parallel plates which contain between them a periodic array of vacuum and n-type semiconductor (or metal) slabs is examined in the presence of a uniform external static magnetic field applied parallel to both the plates and slab surfaces. The photonic band structure for electromagnetic waves propagating in a direction perpendicular to the slab faces is found to be sensitive to the applied magnetic field. Two effects are observed in the presence of a nonzero applied magnetic field: (1) a gap opens in the frequency region 0 < (omega) /c < (pi) /d, where d is the plate separation, and (2) a nonreciprocal structure is generated which yields a band structure that is asymmetric in wavevector space.
